wp-federated-login v0.0.4

This repo is forked from Nightgunner5/node-wordpress-auth. Since The original project is not working on new node versions and is not maintained by the original author anymore, So I decided to update the code to make it work and publish a npm package based on that.

NPM package link: https://www.npmjs.com/package/wp-auth

TO INSTALL:

npm i wp-federated-login

TO USE:

In your init:

var wp_auth = require('wp-federated-login').create({
                      wpurl: 'http://my-blog.example',
                      logged_in_key: 'LOGGED_IN_KEY from wp-config.php',
                      logged_in_salt: 'LOGGED_IN_SALT from wp-config.php',
                      mysql_host: 'MySQL host',
                      mysql_user: 'MySQL username',
                      mysql_pass: 'MySQL password',
		              mysql_port: 'MySQL port (defaults to 3306)',
                      mysql_db: 'MySQL database',
                      wp_table_prefix: 'WordPress table prefix (eg. wp_)' });
                      skipAuthentication: Boolean (send true to bypass hash checking and directly get values from SQL DB)
                      debug: Boolean (send true to enable console logs)
                      maxRetries: Number (Number of retries to connect to mysql if connection fails or some error occurs),
                      cacheTimeout: time after which cache will be invalidated and fresh results will be fetched

When you get a HTTP request and you need to verify auth:

wp_auth.checkAuth( req ).on( 'auth', function( auth_is_valid, user_id ) {
    auth_is_valid; // true if the user is logged in, false if they are not
    user_id; // the ID number of the user or 0 if the user is not logged in
} );

To get a usermeta value:

wp_auth.getUserMeta( user_id, 'meta_key (eg. occupation)', function( data ) {
    // data is null if the user doesn't exist or doesn't have the key.
    // Otherwise, it is the value you would get in WordPress (unserialized intelligently)
} );

To get multiple usermetas value at once:

wp_auth.getUserMetas( user_id, 'meta_keys (in array format e.g [ occupation, salary ])', function( data ) {
    // data is null if the user doesn't exist or doesn't have the key.
    // Otherwise, it is the value in array format : [ {occupation: occupationVal }, { salary: salaryVal } ]
} );

To set a usermeta value:

wp_auth.setUserMeta( user_id, 'meta_key (eg. occupation)', 'meta_value (eg. Eating spaghetti)' );

To get a user_id from a usermeta value:

wp_auth.reverseUserMeta( 'meta_key (eg. occupation)', 'meta_value (eg. Eating spaghetti)', function( id ) {
    // id is null if no user could be found with the given meta key value pair
    // Otherwise, it is the ID of the user
    // If multiple users matched, only one will be given
} );
